Comment

In the former Bufo canaliferus group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 49. See account by Porter, 1964 "1963", Herpetologica, 19: 229–247. Köhler, Veselý, and Greenbaum, 2005 "2006", Amph. Rept. El Salvador: 25-27, provided an account (as Bufo canaliferus, and for El Salvador) and a color photograph. Mendelson, Mulcahy, Williams, and Sites, 2011, Zootaxa, 3138: 1–34, suggested that Incilius canaliferus is a members in an unnamed monophyletic group (the name Incilius marmoreus group is availabe-DRF) that includes Incilius canaliferus, Incilius marmoreus, and Incilius perplexus. Oliver-López, Woolrich-Piña, and Lemos-Espinal, 2009, Fam. Bufonidae Mex.: 61–64, provided an account (as Ollotis canalifera). Köhler, 2011, Amph. Cent. Am.: 104–115, compared this species to others in Central America ad provided a range map and photograph.
